Not accurate on some of them. The 50 prof. for levels one and two must be the characters that are in those stages. I have 3 at 50 prof. and have not gotten those levels. Another guide tells on how you have to be those specific officers...which is a horrible idea

Woah im shocked one thing is to do every dreammode and every storymode on every single difficulty but i never imagine it would be this timeconsuming unlocking dream mode stages. Now i understand why people say this one is timeconsuming. Nevertheless i will finish this one as i so far have 1000 achievments on every koei games so far. I really love WO2. Looking forward to many good hours with that one hehe

Hehe yea it took me quite some time to finish it off i think end result was 82 hours and 45 mins or something . Ehm might be a stupid question but i havent quite figured out the profiency lvl yet. It said in the booklet that its points for every general and 100 soldier u kill? u just continue with that til youre lvl is 50? Also could anyone explain to me what u mean by collect ingredience?

The Profiency is gained by killing things. I am going to pretend it is a point system real quick.

Officer = 100 points
Regular Soliders = 1 point

500 points = 1 profiency

There are lots of wallpapers that are unlocked with each character gaining profiency. I have heard a lot of different things, like it making your character strong in defense, and even someone claimed it added 10% damage every level. I am not sure if any of it is true. One also said it makes your R1 Musou move stronger...I don't even use that button so I hope not!

Thanks. I asked this same question on another thread. Was very confused by the whole proficiency thing. Looks like Koei made this one take an extremely long amount of time to max.

Just get 55 characters to max proficiency to unlock Dream Mode stages and try to get all treasures because 2 characters come from getting treasure while Orochi X is unlocked by beating all Dream Mode stages (some can only be unlocked by getting all treasure and by getting max proficiency for 55 characters).

Thanks for the info, I picked this game up yesterday and have one goal in mind: Sun Wukong. I mean, have you guys read "Journey to the West?" After reading that, you find out that Monkey can beat the crap out of anyone. Orochi would cower away lol
